Starting in 2017, the Republicans will control the federal government (White House, Senate, and House of Representatives). The most the most meaningful opportunity for Democrats/Progressives to hold the Trump administration accountable is to win back the House and the Senate - although winning governorships is far more likely. The earliest we can do this is in the midterm elections of 2018. All 435 seats in the United States House of Representatives and 33 of the 100 seats in the United States Senate will be contested. 38 state and territorial governorships and numerous other state and local elections will also be contested - Virginia and New Jersey take place in 2017.
It may be a lost cause for advancing progressive policies (versus holding-the-line) at the federal level and therefore progressives need to focus on the city and state level. Thus far, I cannot find any centralized index and/or map for all the progressive policies making it easy for people to be informed and take action in their cities and/or states. For example, it would be great if every city around the US became “sanctuary city” and had common sense gun policies.
Obviously there are limits to the power of cities and states, but they have a long history of adopting policies at odds with federal guidance, including regarding healthcare access, marijuana use, and marriage equality, etc. See this helpful chart which shows how a few pioneering states can take on various issues and eventually influence federal policy.
Therefore, having user-friendly indices and corresponding map--with layers for each issue (and organizations within each issue)--could help illustrate the broad support across the country for supporting progressive policies as well as provide a tool to focus attention on the gaps/areas that need attention.
